Figure 4.
The large three-dimensional cube is divided into evenly spaced smaller cubes forming a regular grid. Each face of the cube is segmented into equal square sections. To the right, a smaller three-dimensional cube appears separately. A single circular dot is placed at the centre of one face of the smaller cube. Beneath the smaller cube, a circular dot symbol precedes the text The Grid Center Of The Sub-Voxel.Process diagram of voxel region of interest (RoI) pooling
